This high-capacity transformer is designed to meet your most demanding power distribution needs with unparalleled reliability and performance. Engineered with state-of-the-art oil-immersion technology, this transformer ensures efficient energy transfer and robust durability, making it the ideal choice for both industrial and commercial applications. Trust in TSTY ELECTRIC CO., LTD. to power your success with innovation and excellence.
The rated voltage can be meticulously customized according to each customer's unique requirements, ensuring optimal compatibility and performance.
The state-of-the-art, fully sealed oil-immersed power transformer engineered by TSTY ELECTRIC CO., LTD. boasts
remarkable advantages such as minimal energy loss, whisper-quiet operation, and exceptional efficiency, which collectively contribute to significant energy savings and pollution reduction. Unlike conventional oil-immersed transformers, our fully sealed version eliminates the need for an oil conservator. The oil volume adjustments are seamlessly managed by the elasticity of the corrugated oil tank's sheet, creating a self-regulating system. This innovative design ensures the transformer remains isolated from air, thereby preventing oil deterioration and insulation aging. Consequently, this enhances operational reliability and virtually eliminates the need for maintenance during regular operation.
Main Components:
The main parts of this transformer include the Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank is designed to immerse the windings in oil, ensuring efficient cooling and insulation.
2. Complies with IEC standards and comes with CE/ISO certifications, guaranteeing quality and safety.
3. It can be easily accessed and expanded during loading, allowing the oil temperature to rise and fall as needed.
4. The Buchholz relay is essential when a conservator tank is used. It detects faults such as oil loss and improper oil flow between the tank and transformer, providing early warnings.
5. The Breather Unit contains silica gel that absorbs moisture from the oil. When the gel changes from blue to pink, it indicates it can no longer absorb moisture effectively.
6. The oil indicator shows the oil level within the conservator unit, ensuring proper maintenance and operation.
7. The temperature detector continuously monitors oil temperature. If the temperature exceeds a certain threshold, the transformer will be disconnected from service to prevent damage.
8. The pressure relief device reduces internal pressure within the transformer, preventing potential explosions.
9. The thermal relay serves as a temperature indicator for the windings, ensuring they remain within safe operating limits.
10. Fully galvanized coating ensures no rust, enhancing durability and longevity.
11. The bushing connects the internal windings of the transformer to the external electrical network, facilitating efficient power distribution.
